Difference between the acquisition time of the LIDAR profile and the PARASOL pixel (t_acq_caliop - t_acq_parasol), for each direction. PARASOL pixel acquisition time is computed using the formula : t = first_image_acquisition_time + (sequence_number * 19.6), where 19.6 seconds is the duration of a sequence acquisition

Altitude above mean sea level of the intersection between the pixel viewing direction and the LIDAR profile. This intersection is defined by the point at the intersection between the LIDAR profile and the segment perpendicular to the 2 viewing directions

Half the distance of intersection between the LIDAR profile and the solid angle of the viewed PARASOL pixel. In other words, the intersection is representative in the range "Intersection_Altitude +/- Intersection_Altitude_Range"
